Hey, i got stuck at trying to find solution how to make stage for my project the thing i am aiming is to have nice vertically scrolling backgrounds, all tutorials i find just shows very basic thing for infinity scrolling. So i cant figure way out how to make more advanced things like for example, after you are halfway stage background changes from just clouds but now you are over the ocean, you encounter "mid boss" and background dynamically changes to "infinite" scrolling until you defeat him. I have few ideas how to do it (instancing scenes with extra layers to hide transition) but all of my "ideas" feel like workarounds and not scalable. If somebody encounter similar "problems" maybe you could give an advice.
I hope i was able to convey my question
As for result i am aiming is something like DoDonPachi and similar arcade "shmups"
